The word of God says: “Sanctify yourselves therefore, and be ye holy: for I am the LORD your God” (Leviticus 20:7).
Jesus says: “Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come” (Matthew 12:31-32).
“Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;
As obedient children, not fashioning yourselves according to the former lusts in your ignorance:
But as he which hath called you is holy, so be ye holy in all manner of conversation;
Because it is written, Be ye holy; for I am holy” (1 Peter 21:13-16).
